An Automatic Registration of UV Images

摘要：

　　Corona discharge which occurs on high voltage equipment has being detected by Ultraviolet (UV) imaging technology for these years.Image processing technique is essential for UV detection.Image registration technique is one of important methods for image processing.It is useful for further pattern segment of UV images and recognition study by image registration.In this paper,an image registration approach based on SURF (Speed Up Robust Features) is proposed.Firstly,the feature points were extracted using SURF; then the mapping relationship between images could be achieved using RSA(Random Sampling Algorithm) and least square method; finally,transform parameter matrix could be established.The result of experiments shows that our method can achieve accuracy and practicability.
